Abstract
A semiconductor chip including a semiconductor substrate having first and second surfaces, a transistor on the first surface, a first interlayer dielectric layer on the transistor, a second interlayer dielectric layer on the first interlayer dielectric layer, a wiring line in the second interlayer dielectric layer, a first conductive pad on the second interlayer dielectric layer, a first passivation layer on the second interlayer dielectric layer, a second conductive pad in the first passivation layer, a through via penetrating the semiconductor substrate and the first interlayer dielectric layer to come into connection with the wiring line, a second passivation layer on the second surface, and a third conductive pad in the second passivation layer and connected to the through via. The first passivation layer has a first thickness 0.4 to 0.6 times a second thickness between the first surface and a top surface of the second passivation layer.
